Kubelesyegwa mbuli chintu chakufwambaana kusima, mafuta aakusanzya alubo mbuli chintu chakuyumya simenti. Chibelesyegwa mukuyaka bulo amakonkriti aasiyene-siyene kuchitila kuti sementi ifwambaane kuyuma akufwiinsya chiindi chakuyuma, kampatila muchiindi chamupeyo kuchitila kutabilila kufwambaana kwakuyuma kuti kutabi kuchedwa aawo nokwatontola. Kufwambaana kugwisya, kuchitila kuti sementi ibelesegwe chakufwambaana. Calcium formate ibelesya: misyobo yoonse yazibulo ziyumu, misyobo yoonse yakonkriti, zintu zitakonzyi kubola, makwebo aakubamba bulo, makwebo aazyakulya, kupanga masusu. Kutola lubazu kwa calcium formate akucenjela Mweelwe wa calcium formate mutani lyomwe lyabulongo buyumu a konkriti uli afwaafwi kusika ku 0.5 ~ 1.0%, mpawo mweelwe mupati ngu 2.5%. Mweelwe wa calcium formate ulayungizyigwa asyoonto-syoonto aawo kupya nokwaselemuka. Nikuba kuti mweelwe wa 0.3-0.5% wabikkwa muchiindi chamawulu, ulakonzya kuba anguzu ziboneka kumatalikilo.
